The processor may also be configured to cause the system to determine one or more reconstruction-related algorithms and determine one or more containers for the one or more reconstruction-related algorithms. Each of the one or more containers may correspond to at least one of the one or more reconstruction-related algorithms. The system may also be configured determine a reconstruction flow based on the one or more containers and process the raw data according to the reconstruction flow to generate a target image.

TECHNICAL FIELD

The application generally relates to systems and methods for data processing, and more specifically relates to systems and methods for image reconstruction.

BACKGROUND

Currently, image reconstruction includes online reconstruction and offline reconstruction, and both may need a reconstruction protocol to determine a reconstruction flow. Once the reconstruction protocol is determined, a reconstruction system may process the raw data and generate a target image according to a reconstruction flow determined by the reconstruction protocol. During the process, if the user is not satisfied with the images reconstructed or wants to change the reconstruction flow, the user may need to re-determine a new reconstruction protocol. It may be desirable to provide systems and methods for determining a reconstruction flow dynamically.

FIG. 2 is a schematic diagram illustrating hardware and/or software components of an exemplary computing device on which the processing device 140 may be implemented according to some embodiments of the present disclosure. For example, the processing device 140 may be implemented on the computing device 200 and configured to perform functions of the processing device 140 disclosed in this disclosure.

The computing device 200 may be a general purpose computer or a special purpose computer. Both may be used to implement the processing device 140 of the present disclosure. For example, the processing device 140 of the imaging system 100 may be implemented on the computing device 200, via its hardware, software program, firmware, or a combination thereof. Although only one such computer is shown for convenience, the computer functions related to the imaging system 100 as described herein may be implemented in a distributed manner on a number of similar platforms to distribute the processing load.

The computing device 200, for example, may include communication (COMM) ports 250 connected to and from a network (e.g., the network 120) connected thereto to facilitate data communications.

Merely for illustration purposes, only one processor is described in the computing device 200. However, it should be noted that the computing device 200 in the present disclosure may also include multiple processors. Thus operations that are performed by one processor as described in the present disclosure may also be jointly or separately performed by the multiple processors. For example, the processor of the computing device 200 executes both operation A and operation B. As another example, operation A and operation B may also be performed by two different processors jointly or separately in the computing device 200 (e.g., the first processor executes operation A and the second processor executes operation B, or the first and second processors jointly execute operations A and B).

In some embodiments, a mobile operating system 370 (e.g., iOS™, Android™, Windows Phone™) and one or more applications 380 may be loaded into the memory 360 from the storage 390 to be executed by the CPU 340. The applications 380 may include a browser or any other suitable mobile apps for receiving and rendering information relating to image processing or other information from the processing device 140. User interactions with the information stream may be achieved via the I/O 350 and provided to the processing device 140 and/or other components of the imaging system 100 via the network 120.

To implement various modules, units, and their functionalities described in the present disclosure, computer hardware platforms may be used as the hardware platform(s) for one or more of the elements described herein. A computer with user interface elements may be used to implement a personal computer (PC) or any other type of work station or terminal device.

The acquisition module 402 may be configured to obtain raw data. For example, the acquisition module 402 may obtain raw data of an X-ray image of the object under examination generated by the detector 115. In some embodiments, the acquisition module 402 may obtain the raw data from the CT scanner 110 or the storage device 130.

The algorithm determination module 404 may be configured to determine one or more reconstruction-related algorithms. The reconstruction-related algorithm may include an algorithm related to image reconstruction, or a part of an algorithm related to image reconstruction. In some embodiments, the reconstruction-related algorithm may include Air Correction, Bad Channel, Beam Run, HU Correction, Row Combine, Filter Back Projection (FBP), Image Filter, Ring Off, Windmill, Bone Correction, iterative metal artifact reduction (IMAR), or the like, or any combination thereof, or a part thereof. For example, some algorithms related to image reconstruction may be divided into a plurality of sub-algorithms. The sub-algorithms may be standardized according to certain rules, such as having the same format of input and/or output. The reconstruction-related algorithm may include one or more of the plurality of sub-algorithms.

In some embodiments, the algorithm determination module 404 may determine one or more reconstruction-related algorithms based on the raw data and/or a scan protocol. For example, the one or more reconstruction-related algorithms may be determined based on the object under examination or based on a scan mode, such as axial, helical, spiral. Merely by way of example, the algorithm determining module 404 may determine the Bone Correction in the case that the object under the examination is the head. As another example, the algorithm determining module 404 may determine the FBP algorithm in the case that the scan mode is spiral. In some embodiments, the algorithm determination module 404 may determine one or more reconstruction-related algorithms according to instructions entered by a user (e.g., a doctor) through the terminal 150 or the processing device 140.

The container determination module 406 may be configured to determine one or more containers for the one or more reconstruction-related algorithms determined by the algorithm determination module 404. The container may be associated with a process and implemented on the computing device 200. The container may occupy a resource of the computing device 200 (also called the designated resource), such as the resource of processors and/or memory. A container may contain one or more reconstruction-related algorithms and may execute only one reconstruction-related algorithm at a time. In some embodiments, a container may contain only one reconstruction-related algorithm. As used herein, a container corresponding to a reconstruction-related algorithm refers to the container that contains the reconstruction-related algorithm. The container may be performed to process data according to the reconstruction-related algorithm included therein using the designated resource. In some embodiments, the container may provide a specific circumstance for a reconstruction-related algorithm and may execute a predetermined format of instructions, such as OpenCL, C, C++, Python, etc. The container may be used to process data input according to the contained reconstruction-related algorithm using the designated resource of the computing device 200. In some embodiments, the container may contain a default reconstruction-related algorithm while generated. In some embodiments, each container may have a tag, for example, PRE-1-1, PRE-1-2, IC-1-1, POST-1-1, etc. The tag of the each container may be named according to the reconstruction-related algorithm included therein. The imaging system 100 may dynamically adjust the total number of the containers in the imaging system 100. For example, the imaging system 100 may linearly adjust the total number of the containers in the imaging system 100 based on reconstruction task, e.g., the number of reconstruction processes at the same time.

It should be noted that the container determination module 406 may determine a container for each of the one or more reconstruction-related algorithms determined by the algorithm determination module 404. In some embodiments, the container determination module 406 may determine a container for a reconstruction-related algorithm of the one or more reconstruction-related algorithms by selecting a container that has already been in existence in the processing device 140. Alternatively or additionally, the container determination module 406 may determine a container for a reconstruction-related algorithm of the one or more reconstruction-related algorithms by generating a new container by the processing device 140. Alternatively or additionally, the existing container or the newly generated container may contain any reconstruction-related algorithm, such as a default reconstruction-related algorithm, other than the reconstruction-related algorithm of the one or more reconstruction-related algorithms, and the container determination module 406 may replace the default reconstruction-related algorithm with the reconstruction-related algorithm of the one or more reconstruction-related algorithms. Details about the container determination module 406 may be described elsewhere in this disclosure (e.g., FIGS. 6 and 7, and the description thereof).

The reconstruction flow determination module 408 may be configured to determine a reconstruction flow based on one or more containers. As used herein, the reconstruction flow may represent a data process flow including, e.g., multiple containers that are executed in an order.

In some embodiments, the reconstruction flow determination module 408 may determine the reconstruction flow by arranging the one or more containers in an order based on the contained reconstruction-related algorithm. Details about the reconstruction flow determination module 408 may be described elsewhere in the present disclosure, e.g., FIG. 8 and the description thereof.

The processing module 410 may be configured to process the raw data obtained by the acquisition module 402 according to the reconstruction flow determined by the reconstruction flow determination module 408. In some embodiments, the processing module 410 may generate a target image by processing the raw data according to the reconstruction flow. In some embodiments, the processing module 410 may separate the reconstruction flow into several container groups. Each container group may include at least one container of the reconstruction flow. Details about the processing module 410 may be described elsewhere in the present disclosure, e.g., FIG. 8 and the description thereof.

The storage module 412 may be configured to store obtained the raw data, the data, the images generated in the reconstruction process, the one or more reconstruction-related algorithms, or the like, or any combination thereof. In some embodiments, the storage module 412 may include a mass storage, removable storage, a volatile read-and-write memory, a read-only memory (ROM), or the like, or any combination thereof. The mass storage may include a magnetic disk, an optical disk, a solid-state drive, etc. The removable storage may include a flash drive, an optical disk, a memory card, a zip disk, a magnetic tape, etc. The volatile read-and-write memory may include a random access memory (RAM). The RAM may include a dynamic RAM (DRAM), a double date rate synchronous dynamic RAM (DDR SDRAM), a static RAM (SRAM), a thyristor RAM (T-RAM), and a zero-capacitor RAM (Z-RAM), etc. The ROM may include a mask ROM (MROM), a programmable ROM (PROM), an erasable programmable ROM (EPROM), an electrically erasable programmable ROM (EEPROM), a compact disk ROM (CD-ROM), and a digital versatile disk ROM, etc. In some embodiments, the storage module 412 may store one or more programs and/or instructions that may be executed by the processor 220 of the processing device 140 (e.g., the processing module 410) to perform exemplary methods and/or processes described in the disclosure. For example, the storage module 412 may store programs and/or instructions executed by the processor 220 of the processing device 140 to obtain raw data, determine one or more reconstruction-related algorithm, determine one or more containers, determine a reconstruction flow, reconstruct an image based on the raw data, or display any intermediate result or a resultant image.

The modules of the processing device 140 may be connected to or communicate with each other via a wired connection or a wireless connection. The wired connection may include a metal cable, an optical cable, a hybrid cable, or the like, or any combination thereof. The wireless connection may include a Local Area Network (LAN), a Wide Area Network (WAN), a Bluetooth, a ZigBee, a Near Field Communication (NFC), or the like, or any combination thereof. Two or more of the modules may be combined into a single module, and any one of the modules may be divided into two or more units. For example, the acquisition module 402 and the algorithm determination module 404 may be combined into a single module that may be configured to obtain the raw data and determine the one or more reconstruction-related algorithms based on the obtained raw data.

FIG. 5 is a flowchart illustrating an exemplary process for generating a target image according to some embodiments of the present disclosure. The process 500 may be executed by the processing device 140. For example, the process 500 may be implemented as a set of instructions stored in the ROM 230 or the RAM 240. The processor 220 and/or the modules 402-412 illustrated in FIG. 4 may execute the set of instructions, and when executing the instructions, it may be configured to perform the process 500. The operations of the process 500 presented below are intended to be illustrative. In some embodiments, the process 500 may be accomplished with one or more additional operations not described and/or without one or more of the operations discussed. The order in which the operations of the process 500 illustrated in FIG. 5 and described below is not intended to be limiting.

In 502, the processing device 140 (e.g., the acquisition module 402, the interface circuits of the processor 220) may obtain raw data. In some embodiments, the processing device 140 may obtain the raw data from the CT scanner 110 or the storage device 130.

In 504, the processing device 140 (e.g., the algorithm determination module 404, the processing circuits of the processor 220) may determine one or more reconstruction-related algorithms based on the raw data and/or a scan protocol. For example, the processing device 140 may determine the one or more reconstruction-related algorithms based on the object under examination through which the raw data generated. Alternatively or additionally, the processing device 140 may determine the one or more reconstruction-related algorithms based on the scan mode, such as axial, helical, spiral. In some embodiments, the processing device 140 may determine the one or more reconstruction-related algorithms according to instructions received from a user (e.g., a doctor) through the terminals 150 or the processing device 140.

In 506, the processing device 140 (e.g., the container determination module 406, the processing circuits of the processor 220) may determine one or more containers for the one or more reconstruction-related algorithms determined in 504. For example, the determination of the one or more containers for the one or more reconstruction-related algorithms may include determining a container for each of the one or more reconstruction-related algorithms. In some embodiments, the processing device 140 may obtain a first reconstruction-related algorithm from the one or more reconstruction-related algorithms and determine a container for the first reconstruction-related algorithm by selecting a container that contains the first reconstruction-related algorithm. Alternatively or additionally, the processing device 140 may generate a new container for the first reconstruction-related algorithm and package the first reconstruction-related algorithm into the newly generated container. Alternatively or additionally, the processing device 140 may obtain an existing container, which may contain another algorithm (e.g., another reconstruction-related algorithm), and replace the algorithm included in the container with the first reconstruction-related algorithm. Details about the determination of the container may be described elsewhere in the present disclosure, e.g., FIG. 7 and the description thereof.

In 508, the processing device 140 (e.g., the reconstruction flow determination module 408, the processing circuits of the processor 220) may determine a reconstruction flow based on the one or more containers. It should be noted that an image reconstruction process may need multiple reconstruction-related algorithms. In some embodiments, each of the multiple reconstruction-related algorithms may have at least one function to the input data of the reconstruction-related algorithm, a function of a reconstruction-related algorithm may include a method performed by a processor for processing the input data of the reconstruction-related algorithm. For example, the reconstruction-related algorithm Air Correction may have a function of processing the raw data. The processing device 140 may process the raw data using these reconstruction-related algorithms in a sequence, e.g., an output of a reconstruction-related algorithm of the one or more reconstruction-related algorithms determined in 504 may be an input of another reconstruction-related algorithm of the one or more reconstruction-related algorithms. The processing device 140 may determine a reconstruction flow by arranging the containers in an order based on the reconstruction-related algorithms. For example, the one or more containers may be linked together in the order to form the reconstruction flow. In some embodiments, the processing device 140 may mark each of the one or more containers using a symbol that represents the order in the reconstruction flow that the container may execute the processing based on the corresponding reconstruction-related algorithm. In some embodiments, when a container is occupied by a reconstruction flow, the container may not be linked to any other reconstruction flow at the same time. For example, once a container has been linked to a first reconstruction flow, it may not be used in a second reconstruction flow at the same time. Details about the determination of the container may be described elsewhere in the present disclosure (e.g., FIG. 9 and the description thereof).

In 510, the processing device 140 (e.g., the processing module 410, the processing circuits of the processor 220) may process, according to the reconstruction flow determined in 508, the raw data obtained in 502 to generate a target image. For example, the processing device 140 may execute, use, load, or occupy the one or more containers of the reconstruction flow according to an order to process the raw data. In some embodiments, the processing device 140 may determine several container groups from the one or more containers of the reconstruction flow and process the data based on the container groups. Details about the processing the raw data to generate a target image may be described elsewhere in the present disclosure (e.g., FIG. 11 and the description thereof).

In 512, the processing device 140 (e.g., the reconstruction flow determination module 408, the processing circuits of the processor 220) may release the one or more containers from the reconstruction flow determined in 508 after the processing has finished. In some embodiments, the processing device 140 may release a container from a reconstruction flow once the data processing using the container has finished. Alternatively, the processing device 140 may not release any one container from the reconstruction flow until the whole of the reconstruction flow has been finished. In some embodiments, the processing device 140 may release a container group from a reconstruction flow once the data processing using the container group has finished. It should be noted that only after a container and/or a container group has been released from a first reconstruction flow, a second reconstruction flow may use the container.

It should be noted that the above description is merely provided for illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure. For example, one or more other optional operations (e.g., a storing operation) may be added in the process 500. In the storing operation, the processing device 140 may store information and/or data associated with the reconstruction flow and the containers in a storage device (e.g., the storage device 130, the storage module 412) as described elsewhere in the present disclosure.

FIG. 6 is a block diagram illustrating an exemplary container determination module according to some embodiments of the present disclosure. The container determination module 406 may include an algorithm acquisition unit 602, a container search unit 604, a container generation unit 606, a container switch unit 608, and a container determination unit 610.

The algorithm acquisition unit 602 may be configured to obtain a reconstruction-related algorithm from the one or more reconstruction-related algorithms determined by processing device 140 (e.g., the algorithm determination module 404). In some embodiments, the algorithm acquisition unit 602 may obtain one reconstruction-related algorithm once a time. In some embodiments, the algorithm acquisition unit 602 may obtain multiple reconstruction-related algorithms once a time.

The container search unit 604 may be configured to search a container containing a reconstruction-related algorithm. For example, the container search unit 604 may search and determine whether there exists a container containing the reconstruction-related algorithm obtained by the algorithm acquisition unit 602. In some embodiments, containers that are not included in any other reconstruction flow are searchable. In some embodiments, the container search unit 604 may search and determine whether there exists a container containing an additional reconstruction-related algorithm other than the reconstruction-related algorithm obtained by the algorithm acquisition unit 602 and not included in any other reconstruction flow.

The container generation unit 606 may be configured to generate a container in the processing device 140. In some embodiments, the container generation unit 606 may generate a container containing the reconstruction-related algorithm obtained by the algorithm acquisition unit 602. In some embodiments, the container generation unit 606 may generate a container containing a default reconstruction-related algorithm. In some embodiments, the container generation unit 606 may generate a container based on the resource of the processing device 140, such as the processing units and/or the memory available or to be available.

The container switch unit 608 may be configured to switch a first reconstruction-related algorithm to a second reconstruction-related algorithm in a container. For example, by disconnecting the container and the first reconstruction-related algorithm, and connecting the container with the second reconstruction-related algorithm, the container switch unit 608 may replace the first reconstruction-related algorithm with the second reconstruction-related algorithm in the container.

In some embodiments, the container switch unit 608 may obtain a first reconstruction-related algorithm obtained by the algorithm acquisition unit 602, and obtain an existing container containing a second reconstruction-related algorithm determined by the container search unit 604. In some embodiments, the second reconstruction-related algorithm may be a reconstruction-related algorithm that is different from the first reconstruction-related algorithm. The container switch unit 608 may replace the second reconstruction-related algorithm with the first reconstruction-related algorithm. In some embodiments, the container switch unit 608 may obtain the first reconstruction-related algorithm obtained by the algorithm acquisition unit 602, and obtain a container containing a default reconstruction-related algorithm generated by the container generation unit 606. The container switch unit 608 may replace the default reconstruction-related algorithm with the first reconstruction-related algorithm.

The container determination unit 610 may be configured to determine a container for the reconstruction-related algorithm obtained by the algorithm acquisition unit 602. For example, the container determination unit 610 may determine an existing container as the container for the first reconstruction-related algorithm on an occurrence that the container search unit 604 determines that the existing container contains the reconstruction-related algorithm obtained by the algorithm acquisition unit 602, and not connects to any other reconstruction flow. In some embodiments, the container determination unit 610 may determine a container containing an additional reconstruction-related algorithm as the container for the first reconstruction-related algorithm after the container switch unit 608 has replaced the additional reconstruction-related algorithm with the reconstruction-related algorithm. In some embodiments, the container determination unit 610 may determine a container generated by the container generation unit 606 as the container for the first reconstruction-related algorithm. Details about the determination of the container may be described elsewhere in the present disclosure (e.g., FIG. 7 and the description thereof).

The units (e.g., the algorithm acquisition unit 602, the container search unit 604, the container generation unit 606, the container switch unit 608, the container determination unit 610) of the container determination module 406 may be connected to or communicate with each other via a wired connection or a wireless connection. The wired connection may include a metal cable, an optical cable, a hybrid cable, or the like, or any combination thereof. The wireless connection may include a Local Area Network (LAN), a Wide Area Network (WAN), a Bluetooth, a ZigBee, a Near Field Communication (NFC), or the like, or any combination thereof. Two or more of the units may be combined into a single unit, and any one of the units may be divided into two or more sub-units. For example, the algorithm acquisition unit 602 and the container generation unit 606 may be combined into a single unit that may both obtain a first reconstruction-related algorithm from the one or more reconstruction-related algorithms and generate a container for the first reconstruction-related algorithm. As another example, the container determination module 406 may include a storage unit (not shown) used to store information and/or data associated with the reconstruction-related algorithm.

FIG. 7 is a flowchart illustrating an exemplary process for determining a container for a reconstruction-related algorithm according to some embodiments of the present disclosure. The process 700 may be executed by the processing device 140. For example, the process 700 may be implemented as a set of instructions stored in the ROM 230 or the RAM 240. The processor 220 and/or the units 602-610 illustrated in FIG. 6 may execute the set of instructions, and when executing the instructions, it may be configured to perform the process 700. The operations of the process 700 presented below are intended to be illustrative. In some embodiments, the process 700 may be accomplished with one or more additional operations not described and/or without one or more of the operations discussed. Additionally, the order in which the operations of the process illustrated in FIG. 7 and described below is not intended to be limiting. In some embodiments, at least part of the operation 506 of the process 500 may be performed according to the process 700.

In 702, the processing device 140 (e.g., the algorithm acquisition unit 602, the interface circuits of the processor 220) may obtain a first reconstruction-related algorithm from the one or more reconstruction-related algorithms determined by the algorithm determination module 404. The first reconstruction-related algorithm used herein may represent any one of the one or more reconstruction-related algorithms.

In 704, the processing device 140 (e.g., the container search unit 604, the processing circuits of the processor 220) may determine whether there is an existing container containing the first reconstruction-related algorithm obtained in 702 by searching the imaging system 100 (e.g., storage device 130, processing device 140, or terminal 150). It should be noted that there may be a plurality of containers in the imaging system 100, and each of the containers may contain a reconstruction-related algorithm. If there is such a container and the container is not connected to any other reconstruction flow, the process 700 may proceed to operation 712. Otherwise, the process 700 may proceed to operation 706.

In 706, the processing device 140 (e.g., the container search unit 604, the processing circuits of the processor 220) may determine whether there is a container containing a second reconstruction-related algorithm by searching in the imaging system 100 (e.g., storage device 130, processing device 140, or terminal 150). It should be noted that the second reconstruction-related algorithm used herein may be any reconstruction-related algorithm other than the first reconstruction-related algorithm. If there is such a container and the container is not connected to any other reconstruction flow, the process 700 may proceed to 708. Otherwise, the process 700 may proceed to 710. In some embodiments, each container may be marked with a symbol (e.g., a sequence number) based on the position in the reconstruction flow that the container processes the input data. For example, a container PRE-1-1 processing the raw data may be marked with 0101, and a container IC-1-1 processing the output data of the PRE-1-1 container may be marked with 0102, etc. Once a container has been marked with a symbol, which means the container has been included in a reconstruction flow (e.g., the first reconstruction flow), it may not be used in a second reconstruction flow at the same time.

In 708, the processing device 140 (e.g., the container switch unit 608, the processing circuits of the processor 220) may obtain the container containing the second reconstruction-related algorithm and then replace the second reconstruction-related algorithm with the first reconstruction-related algorithm. Thus, the container containing the second reconstruction-related algorithm may be switched into a container containing the first reconstruction-related algorithm.

In 710, the processing device 140 (e.g., the container generation unit 606, the processing circuits of the processor 220) may generate a container for the first reconstruction-related algorithm. In some embodiments, the container generation unit 606 may generate a container containing any reconstruction-related algorithm, such as a default reconstruction-related algorithm. The default reconstruction-related algorithm may be different from the first reconstruction-related algorithm. The processing device 140 (e.g., the container switch unit 608, the processing circuits of the processor 220) may replace the default reconstruction-related algorithm with the first reconstruction-related algorithm as described in 708. In some embodiments, the container generation unit 606 may generate a container containing the first reconstruction-related algorithm.

In 712, the processing device 140 (e.g., the container determination unit 610, the processing circuits of the processor 220) may determine the container for the first reconstruction-related algorithm. For example, on the occurrence that there is a container containing the first reconstruction-related algorithm (i.e., the “yes” arrow out of 706), and in 712, the processing device 140 may determine the container for the first reconstruction-related algorithm. In some embodiments, the process 700 may proceed to operation 712 from operation 708, and the processing device 140 may determine the switched container for the first reconstruction-related algorithm. In some embodiments, the process 700 may proceed to operation 712 from operation 710, and the processing device 140 may determine the generated container for the first reconstruction-related algorithm.

It should be noted that the above description is merely provided for illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure. For example, one or more other optional operations (e.g., a storing operation) may be added elsewhere in the process 700. In the storing operation, the processing device 140 may store information and/or data associated with the reconstruction-related algorithms and the containers in a storage device (e.g., the storage device 130, the storage module 412) described elsewhere in the present disclosure. In some embodiments, operation 704 may be omitted, and the process 700 may proceed to operation 706 from operation 702. In some embodiments, operations 706 and 708 may be omitted, and the process 700 may proceed to operation 710 from operation 704, on the occurrence that the determination in 704 is no. In some embodiments, operations 704, 706, and 708 may be omitted, and the process 700 may proceed to operation 710 from operation 702. Besides, for persons having ordinary skills in the art, it should be noted that the process 700 is merely provided for illustrating the determination of a container for a reconstruction-related algorithm. Thus, in the determination of the one or more containers for the one or more reconstruction-related algorithms, the process 700 may repeatedly be performed. Moreover, each determination of the container for a reconstruction-related algorithm (i.e., each execution of the process 700) may use different processes of the multiple variations and modifications described above.

FIG. 8 is a block diagram illustrating an exemplary reconstruction flow determination module according to some embodiments of the present disclosure. The reconstruction flow determination module 408 may include a container acquisition unit 802, a reconstruction flow determination unit 804, and a container release unit 806.

The container acquisition unit 802 may be configured to obtain one or more containers determined by the container determination module 406.

The reconstruction flow determination unit 804 may be configured to determine a reconstruction flow by arranging the one or more containers in an order based on the reconstruction-related algorithms included in the containers. Each of the containers may have input data, and the containers may process the input data according to the contained reconstruction-related algorithm, and generate output data. In some embodiments, a container's output data may be another container's input data. In some embodiments, the reconstruction flow determination unit 804 may mark each container with a symbol (e.g., a sequence number) based on the position in the order that the container processes the input data. For example, a container PRE-1-1 processing the raw data may be marked with 0101, and a container IC-1-1 processing the output data of the PRE-1-1 container may be marked with 0102, etc. A container may only be included in one reconstruction flow at a time. For example, once a container has been marked with a symbol, which means the container has been included in a reconstruction flow (e.g., the first reconstruction flow), it may not be used in a second reconstruction flow at the same time.

A reconstruction flow may be performed by the processing device 140 to reconstruct an image based on raw data. For example, the processing device 140 may run the reconstruction flow by executing the one or more containers according to the order to process the raw data and generate a target image.

The container release unit 808 may be configured to release one or more containers from a reconstruction flow. In some embodiments, the container release unit 808 may release the container from a reconstruction flow after the processing of the container has finished. Alternatively or additionally, the container release unit 808 may release all containers from a reconstruction flow after the image reconstruction has finished, e.g., after a target image has been reconstructed.

The units (e.g., the container acquisition unit 802, the reconstruction flow determination unit 804, the container release unit 806) of the reconstruction flow determination module 408 may be connected to or communicate with each other via a wired connection or a wireless connection. The wired connection may include a metal cable, an optical cable, a hybrid cable, or the like, or any combination thereof. The wireless connection may include a Local Area Network (LAN), a Wide Area Network (WAN), a Bluetooth, a ZigBee, a Near Field Communication (NFC), or the like, or any combination thereof. Two or more of the units may be combined into a single unit, and any one of the units may be divided into two or more sub-units. For example, the container acquisition unit 802 and the reconstruction flow determination unit 804 may be combined into a single unit that may both obtain one or more containers and arrange the one or more containers in an order. As another example, the reconstruction flow determination module 408 may include a storage unit (not shown) used to store information and/or data associated with the one or more containers.

FIG. 9 is a flowchart illustrating an exemplary process for determining a reconstruction flow according to some embodiments of the present disclosure. The process 900 may be executed by the processing device 140. For example, the process 900 may be implemented as a set of instructions stored in the ROM 230 or the RAM 240. The processor 220 and/or the units 802-806 illustrated in FIG. 8 may execute the set of instructions, and when executing the instructions, it may be configured to perform the process 900. The operations of the process 900 presented below are intended to be illustrative. In some embodiments, the process 900 may be accomplished with one or more additional operations not described and/or without one or more of the operations discussed. Additionally, the order in which the operations of the process illustrated in FIG. 9 and described below is not intended to be limiting. In some embodiments, the operation 508 may be performed according to the process 900.

In 902, the processing device 140 (e.g., the container acquisition unit 802, the interface circuits of the processor 220) may obtain one or more containers determined by the container determination module 406.

In 904, the processing device 140 (e.g., the reconstruction flow determination unit 804, the processing circuits of the processor 220) may arrange the one or more containers in an order based on the reconstruction-related algorithms included in the containers. Each of the containers may have input data, and the containers may process the input data according to the contained reconstruction-related algorithm, and generate output data. In some embodiments, a container's output data may be another container's input data. The reconstruction flow determination unit 804 may mark each container with a symbol (e.g., a sequence number) based on the position in the sequence that the container processes the input data. For example, a container PRE-1-1 processing the raw data may be marked with 0101, and a container IC-1-1 processing the output data of the PRE-1-1 container may be marked with 0102, etc. Merely by way of example, the one or more containers may include a first container PRE-1-1 containing reconstruction-related algorithm Air Correction, a second container IC-1-1 containing reconstruction-related algorithm FBP algorithm, and a third container POST-1-1 containing reconstruction-related algorithm Image Filter. The input of the first container PRE-1-1 is the raw data, and output is image data. For example, the reconstruction-related algorithm Air Correction may be executed to correct the raw data. As used herein, the image data may represent a corrected raw data, or data used to generate a target image directly. The input of the second container IC-1-1 is the image data (i.e., the output of the first container PRE-1-1 containing reconstruction-related algorithm Air Correction), and the output is a preliminary image (e.g., reconstruction-related algorithm FBP algorithm may be executed to create an image). As used herein, the preliminary image may represent an image generated from the image data without any post-processing. The input of the third container POST-1-1 is the preliminary image generated according to the second container IC-1-1 containing reconstruction-related algorithm FBP algorithm, and the output is a target image (e.g., the third container POST-1-1 containing reconstruction-related algorithm Image Filter may be executed to post-process the preliminary image). As used herein, the target image may represent an image that a user (e.g., a doctor) needs. The processing device 140 may mark the first container PRE-1-1 with symbol 0101, the second container IC-1-1 with symbol 0102, and the third container POST-1-1 with symbol 0103.

In 906, the processing device 140 (e.g., the reconstruction flow determination unit 804, the processing circuits of the processor 220) may determine a reconstruction flow based on the one or more containers according to the order arranged in 904. A container may only be included in one reconstruction flow at a time. For example, once a container has been marked with a symbol which means the container has been included in a first reconstruction flow, it may not be used in a second reconstruction flow. In other words, the container included in the first reconstruction flow may only process the data associated with the raw data. Merely by way of example, the processing device 140 may determine the reconstruction flow including the first container PRE-1-1 containing reconstruction-related algorithm Air Correction, the second container IC-1-1 containing reconstruction-related algorithm FBP algorithm, and the third container POST-1-1 containing reconstruction-related algorithm Image Filter, and according to the order of 0101-0102-0103.

It should be noted that the above description is merely provided for illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure. For example, one or more other optional operations (e.g., a storing operation) may be added elsewhere in the process 900. In the storing operation, the processing device 140 may store information and/or data associated with the one or more containers in a storage device (e.g., the storage 140) described elsewhere in the present disclosure.

In some embodiments, the container group determination unit 1004 may determine a first container group by selecting at least one container from the one or more containers of a reconstruction flow. For example, the at least one container in the first container group may be executed to pre-process the raw data to generate image data. Alternatively or additionally, the container group determination unit 1004 may further determine a second container group by selecting at least one container from the one or more containers of the reconstruction flow. For example, the at least one container in the second container group may be executed to process the image data generated using the first container group to generate a target image.

At least one of the third container group or the fourth container group may include a container from the at least one container of the second container group. The at least one container in the third container group may be executed to process the image data generated by the first container group to generate a preliminary image. The at least one container in the fourth container group may be executed to process the preliminary image generated by the third container group to generate the target image.

It should be noted that a reconstruction flow may include one or more process, such as a pre-process for the raw data, an image creating process for the pre-processed data, e.g., the image data. In some embodiments, the reconstruction flow may further include a post-process, e.g., a process for an image generated by the process for the image data, e.g., the preliminary image. A container group may correspond to at least one process of the reconstruction flow.

The processing unit 1006 may be configured to process data using the one or more containers determined by the container determination module 406. Alternatively or additionally, the processing unit 1006 may process data using the container group determined by the reconstruction flow determination unit 804.

The units (e.g., the acquisition unit 1002, the container group determination unit 1004, the processing unit 1006) of the processing module 410 may be connected to or communicate with each other via a wired connection or a wireless connection. The wired connection may include a metal cable, an optical cable, a hybrid cable, or the like, or any combination thereof. The wireless connection may include a Local Area Network (LAN), a Wide Area Network (WAN), a Bluetooth, a ZigBee, a Near Field Communication (NFC), or the like, or any combination thereof. Two or more of the units may be combined into a single unit, and any one of the units may be divided into two or more sub-units. For example, the acquisition unit 1002 and the container group determination unit 1004 may be combined into a single unit that may both obtain a reconstruction flow and determine one or more container groups from the one or more containers. As another example, the processing module 410 may include a storage unit (not shown) used to store information and/or data associated with the one or more container groups.
